Lewis Tierney, the eldest son of Wigan legend Jason Robinson, will get the chance to fill Sam Tomkins's shoes before the end of the season, Warriors' coach Shaun Wane has revealed.

As Wane prepares to give the scrum-half George Williams his Super League debut in game against London Broncos, he said the 18-year-old Tierney was edging closer to making his bow.

Wane said Tierney, who been with the club since he was 12, was a potential replacement for Tomkins if and when the England star leaves for Australia, which could be as soon as next season.

"He's just back from a serious knee injury but in the two games he's played since then, he's been outstanding," Wane said. "I think in 12 months you'll see a possible full-back there. He's a good player. He has the same attributes Jason had."
